[Dilusion]

I installed Qval 111 on our Linux-Server a few days ago.Worked fine except that once in a while i would get kicked for hook. All of a sudden im getting kicked everytime i try to join, most of the time directly after the QVal_Checks but sometimes 1 or 2 minutes later. Server log looks like this:

QValidate Client-side error!!!
Player is has applied illegal DLL hooks!
Player Name : [AoD]Dilusion
Player IP : 84.135.240.244:1065
Hooks :
In 'D:\Games\UT\System\IpDrv.dll'

Im kinda sure i didnt install smth new on the server or my pc so im a bit curious why just suddenly happens all the time. Anyone experienced smth similar and got an idea ?

Server is Linux v440, Qval+Pure7C+mmc.
